Denso IUF22 Iridium Spark Plug

Maximize your engine's performance with the Denso IUF22 Iridium Spark Plug. Engineered for superior ignition and longevity, this spark plug delivers reliable starts and optimized combustion. Experience the difference of Denso's advanced technology.

Description

The Denso IUF22 Iridium Spark Plug is designed for the demanding needs of high-performance engines. Featuring an iridium electrode, six times harder than platinum, this spark plug withstands temperatures up to 4,000°F, ensuring exceptional durability and spark consistency. The ultra-fine 0.4mm iridium electrode reduces voltage requirements and enhances firing performance, leading to improved fuel efficiency and throttle response. The 360° laser welding of the electrode creates a robust seal, resisting wear and tear even in extreme conditions. Furthermore, the ground electrode incorporates a tapered cut and U-groove, increasing the flame volume and promoting more complete combustion. Upgrade to Denso Iridium spark plugs for unparalleled reliability and performance. This spark plug features a 10 mm thread size and a 12.7 mm (1/2") thread reach, ensuring compatibility with a wide range of engines.
